WARNING

■

Replacing a flat tire

●

Observe the following precautions.

Failure to do so may result in serious

injury:

• Do not try to remove the wheel orna-

ment by hand. Take due care in han-

dling the ornament to avoid

unexpected personal injury.

• Do not touch the disc wheels or the

area around the brakes immediately

after the vehicle has been driven.

After the vehicle has been driven the

disc wheels and the area around the

brakes will be extremely hot. Touching

these areas with hands, feet or other

body parts while changing a tire, etc.

may result in burns.

●

Failure to follow these precautions

could cause the wheel nuts to loosen

and the tire to fall off, resulting in death

or serious injury.

• Never use oil or grease on the wheel

bolts or wheel nuts.

Oil and grease may cause the wheel

nuts to be excessively tightened, lead-

ing to bolt or disc wheel damage. In

addition, the oil or grease can cause

the wheel nuts to loosen and the wheel

may fall off, causing an accident and

resulting in death or serious injury.

Remove any oil or grease from the

wheel bolts or wheel nuts.

• Have the wheel nuts tightened with a

torque wrench to 103 N•m (10.5

kgf•m, 76 ft•lbf) as soon as possible

after changing wheels.

• When installing a tire, only use wheel

nuts that have been specifically

designed for that wheel.

• If there are any cracks or deformations

in the bolt screws, nut threads or bolt

holes of the wheel, have the vehicle

inspected by any authorized Lexus

retailer or Lexus authorized repairer,

or any reliable repairer.

• Do not attach a heavily damaged

wheel ornament, as it may fly off the

wheel while the vehicle is moving.

●

Observe the following precautions.

(Type C)

Failure to do so may result in serious

injury:

560

7-2. Steps to take in an emergency

Remove any dirt or foreign matter
from the wheel contact surface.

If foreign matter is on the wheel contact

surface, the wheel nuts may loosen while

the vehicle is in motion, causing the tire to

come off.

Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.


